WRENCH. l

To all whom, t may concern f' Be it known that I, FRANK A. COLLIER, a citizen of the United States of America, re-

siding at Galveston, in the county of Gal! veston and State of Texas, have invented new and useful Improvements-in Wrenches, of which the following is a specification.

The present invention relates to imprbvements in that class of wrenches known as sliding jaw and the primary object of the invention is vto produce a wrench of an effective and durable construction, which mayv be cheaply manufactured and easily vand quickly operated. With the above and -other objects in view,

the improvement resides in the constructicn,

- combination and arrangement of pafts set,

forth in -the following specication. and falling within the scope of the appended claim. f i

In the drawing there has been illustrated looking in the direction of the arr sa.

In the accompanying drawing, ne|nu. meral 1 designates the 'outer 4jaw of fthe wrench, which is curved upon its opposite faces, its inner or working face being 'provided with teeth 2. The jaw is provided upon one of its. ends with an integrally formed angularly -arranged kshank 3, which is preferably rectangular 1n cross sectlon.

The numeral 4 designates :the inner jaw,.

the' opposite faces` of lwhich, being also curved and the, outer or working face being provided with'teeth 5. The liaw is in.- tegrally formed with anangularly extending shank -or leverv 6, and the saidleverv has its end, (provided with the jaw/i) formed with a substantially rectangular yoke 7 which receives the shank 3 of the jaw 1. so

that the said shank is`arranged over 4one ofV .the faces of the lever 6.

roundedvinwardly, the said roundedl por.

tion being formed with threads 8, and the opposite sides of the said lever. are pro; vided with centrally arranged.. longitud`1- nally extending grooves 9 9. AArranged to travel upon 4the lever 6 -is a carriage 10, the same having pivotallyarranged within a 'suitable opening, a turning screw 11, the

threads of the Said screw being milled to facilitate` themanipulation. of the same, and

Vthe said threads engage with the threads 8 of the lever` 6. The carriage10 ,.is, of

,' course, provided with an opening for. the

reception ofthe lever 6, and the sides of the' said carriage at the opening thereoffare.

formed with lugs or tongues 12 which are received within the grooves 9 of said lever.

The opening through which the lever is vpassed is preferably extended to the 'upper or outer closed end-13 of said carriage.l and the sides of theA carriage, above' or opposite the lever 6, are formed with elongated openings 14 which receive trunnions .15 provided upon the opposite sides of the shank, the vsaid shank being passedthrough -theopening in the carriage. 1 Secured to theend of the shank 3 and bearing upon the lever 6;' I, I is a fiat spring 18 which has a tendencytoI move the shankto tilt, the same te ,bring= the jaw 1 toward the jaw 4.

' From the above descrlption, taken incoi nection'` with the accompanying drawing,4 i'

the simplicity of the device as well as' the advantages thereof will, it Ais thought, he

perfectly apparent to those skilled in the asA art to whichsuch invention appertain's` With' Y out further detailed description.

A wrench including a stationary jaw having a yoke member integral therewith and an angularly Vtoothed shank havingits opposite vsides grooved longitudinally, a I

movable jaw having a shank passing loosely through the yoke of thc stationary jaw. a

carriage upon the shank of the stationary jaw havingflugs received in the grooves thereof and provided witha screw engaging with thev teeth of said jaw, said carnage having an opening to receive the end of the shank of the 'movable jaw` and a shankv Y having lateraltrunnions extending through elong ted openings in. the sides of said car- In testimony whereof vI afX myV signariage, and a spring secured to theends of ture n presence of two Witnesses.' the mentioned shank of the movable jaw and ha'ving its end curved .and bearing l Vtnesses; v against one of the edges of the shank of the A GEO.
